Connect the Air Supply
Recommended air inlet pressure is 60-100 psi [4,1 - 6,9 bar].
1. See Figure 5. Connect a 9 CFM [15 m
supply source to the
swivel connector (B). Use only
disconnect fittings. Larger, heavier fittings are not
recommended. Use a high-grade pipe thread sealer to seal
the connection.
2. Tighten pipe connections securely, but DO NOT OVER-TIGHTEN.
NOTE: To promote long, trouble free pump operation, install an Enerpac air filter
regulator in the air line.
Adjust Hydraulic Pressure
The hydraulic pressure output of your air pump is controlled by the air pressure into the
pump. Increasing the air inlet pressure will increase hydraulic output pressure, and
decreasing air inlet pressure will decrease the hydraulic output pressure.
WARNING
NEVER remove swivel air connector while air line is pressurized. Removing a
pressurized air line may lead to personal injury or equipment damage.
Automatic Pressure Make-up
1. Adjust the air inlet pressure to the pump so that the hydraulic pressure output at stall
corresponds to the desired circuit pressure.
2. Secure the treadle in the advance position. (A treadle clip is supplied with the PA-136
and PA-1150.)
3. With the air supply pressure continuously applied to the air motor, the pump will
automatically cycle whenever circuit hydraulic pressure drops below the pump stall
pressure.
NOTE: These pumps are not recommended for extended stall cycles.
CAUTION
The treadle should only be tied down when continuous oil flow is required to
maintain constant pressure. DO NOT tie treadle for normal pump start/stop
operations.
